Description

Technical Field

[0001] The utility model belongs to the technical field of disconnecting switches, and specifically relates to a static contact installation structure. Background Art

[0002] The static contact is a key component in a disconnecting switch. It, together with the moving contact, ensures the reliable connection and disconnection of the circuit. The static contact is usually fixed on the base or bracket of the disconnecting switch, while the moving contact can move to contact or separate from the static contact. The design and materials of the static contact are crucial for the performance of the disconnecting switch. They need to have good electrical conductivity, low contact resistance, high anti-welding performance, and arc erosion resistance.

[0003] In the current prior art, after long-term use, the traditional static contact installation structure may cause the static contact to become loose. When the contact part of the static contact contacts with the moving contact, poor contact may occur, resulting in a short circuit of the circuit and damage to the switch. This not only reduces the service life of the disconnecting switch but also reduces the practicality of the static contact.

[0004] Therefore, a static contact installation structure is proposed to solve the above problems. Summary of the Utility Model

[0023] The following gives specific embodiments.

[0024] Please refer to Figure 1 - Figure 4, the present utility model provides a static contact installation structure, including an installation box 1. A plurality of installation slots 16 are provided in the middle of the installation box 1. Rectangular slots 2 are provided at both ends of each installation slot 16. The plurality of rectangular slots 2 are all provided at both ends of one side of the installation box 1, and the plurality of rectangular slots 2 are arranged in an array. Two first threaded holes 11 are provided in the middle of each rectangular slot 2. A static contact 4 is sleeved inside each rectangular slot 2. One side of each static contact 4 is adhesively connected to one side of the rectangular slot 2. One end of each static contact 4 is fixedly connected with a contact part 5, and each contact part 5 is arranged on both sides of the installation slot 16 through the static contact 4. Two installation holes 6 are provided in the middle of each static contact 4. A fixing screw 7 is threadedly connected to the inner wall of each installation hole 6. One end outer wall of each fixing screw 7 is threadedly connected to the inner wall of the first threaded hole 11, and each static contact 4 is fixedly connected to the inside of the rectangular slot 2 through two fixing screws 7. Positioning grooves 41 are provided on both sides of each static contact 4. A positioning block 3 is snap-fitted to the inner wall of each positioning groove 41. One side of each positioning block 3 is fixedly connected to the inner wall of the rectangular slot 2. And both sides of each static contact 4 are snap-fitted to the inner wall of the rectangular slot 2 through the positioning block 3.

[0025] During operation, by placing the static contact 4 inside the rectangular slot 2, and clamping the positioning groove 41 outside the positioning block 3, and then pressing the static contact 4 so that the positioning groove 41 is snap-fitted with the outside of the positioning block 3, the static contact 4 can be quickly positioned and installed. Then pass the fixing screw 7 through the installation hole 6 and insert one end of it into the first threaded hole 11, and then rotate the fixing screw 7 to screw it into the inside of the first threaded hole 11, so that the static contact 4 is fixed inside the rectangular slot 2. Further, the contact part 5 is fixed on both sides of the installation slot 16. The arrangement of the installation slot 16 facilitates the staff to install the moving contact, so that the moving contact can stably contact the outside of the contact part 5, thereby improving the stability of the structure. By adopting the above method, the static contact 4 is fixed by two fixing screws 7, which can further improve the stability efficiency of the static contact 4 and reduce the loosening between the structures after long-term use. The situation that the disconnector has poor contact and causes the circuit breaker to be damaged can be reduced, the service life of the disconnector can be improved, and the practicability of the static contact can be improved.

[0026] Further, as Figure 2 and Figure 3 shown, an arc-shaped groove 14 is provided between every two installation slots 16. Rectangular blocks 13 are provided at both ends of each arc-shaped groove 14. One side of each rectangular block 13 is fixedly connected to one side of the installation box 1, and every two rectangular blocks 13 are symmetrically arranged. One side of each rectangular block 13 is provided with a through hole 15. Each through hole 15 is provided on the inner wall of the installation box 1, and the plurality of through holes 15 are arranged in an array.

[0027] During operation, the arc-shaped groove 14 is provided to facilitate the positioning and installation of the moving contact by the operator. Then, the rectangular block 13 can be used to position and install the box body of the disconnecting switch. The long screw is screwed into the through hole 15 to fix the cover plate of the disconnecting switch on the top of the installation box 1, making it convenient for the operator to operate and improving the usage efficiency of the structure.

[0028] Furthermore, as Figure 4 shown, a positioning hole 8 is provided in the inner wall of one end of each static contact 4, and a wiring screw 9 is threadedly connected to the inner wall of each positioning hole 8. A gasket 10 is rotatably connected to the outer wall of each wiring screw 9, and one side of each gasket 10 is adhesively connected to one side of the static contact 4 through the wiring screw 9. A second threaded hole 12 is threadedly connected to the outer wall of one end of each wiring screw 9, and each second threaded hole 12 is provided in the inner wall of one end of the rectangular groove 2.

[0029] During operation, after the static contact 4 is installed inside the rectangular groove 2, when an external circuit needs to be connected, the wiring screw 9 is rotated to remove it, and then one end of the circuit is wound around the outside of the wiring screw 9, or the circuit connector is attached to one side of the static contact 4. Then, the gasket 10 is sleeved on the outside of the wiring screw 9, and the wiring screw 9 is inserted into the positioning hole 8. Then, the wiring screw 9 is rotated to connect it to the inside of the second threaded hole 12, and the gasket 10 is used to press the circuit connector, thereby fixing the circuit connector on the outside of one end of the static contact 4 and ensuring the stability of the connection between the circuit and the static contact 4.

[0030] Working principle: The static contact 4 is placed inside the rectangular groove 2, and the positioning groove 41 is stuck on the outside of the positioning block 3. Then, the static contact 4 is pressed to engage the positioning groove 41 with the outside of the positioning block 3, enabling the quick positioning and installation of the static contact 4. Then, the fixing screw 7 is passed through the mounting hole 6 and one end of it is inserted into the first threaded hole 11, and the fixing screw 7 is rotated to screw it into the inside of the first threaded hole 11, fixing the static contact 4 inside the rectangular groove 2. Thus, the contact part 5 is fixed on both sides of the mounting groove 16, and the provision of the mounting groove 16 facilitates the operator to install the moving contact. After the static contact 4 is installed inside the rectangular groove 2, when an external circuit needs to be connected, the wiring screw 9 is loosened and removed, and then one end of the circuit is wound around the outside of the wiring screw 9, or the circuit connector is attached to one side of the static contact 4. Then, the gasket 10 is sleeved on the outside of the wiring screw 9, and the wiring screw 9 is inserted into the positioning hole 8. Then, the wiring screw 9 is rotated to connect it to the inside of the second threaded hole 12, and the gasket 10 is used to press the circuit connector, thereby fixing the circuit connector on the outside of one end of the static contact 4. Then, the rectangular block 13 can be used to position and install the box body of the disconnecting switch. The long screw is screwed into the through hole 15 to fix the cover plate of the disconnecting switch on the top of the installation box 1.
